I posted not long ago about a young colleague who's said I'm posh a couple of times and things like "Oh I thought you'd be too posh to say something like that."
She hasn't said that since, but it's other things. I have quite a long first and last name and a dual nationality. She told me that my name sounds like some sort of weird recipe and joked "What was my Mum thinking."
I used to have a pixie haircut and I've been growing it for nearly a year, it's a short bob now. She looked at the picture and said "Well it hasn't grown much since last year has it!"
Then other times she's really nice, I don't get it. I find it hard to be assertive because her relative is the boss where we work, plus if it's just me and her working together I don't want to make things awkward. She's likely just immature. Any advice? Am I just being too sensitive?
